In the paper a RFID automatic railway vehicle identification system is treated, consisted of readers, deployed along railroad tracks and tags clipped to the passing vehicles. The reader – tag setup including a reader wake-up sensor is described. The semiactive tags are assumed in this application to achieve a satisfactory long range operation and simultaneously a long tag lifetime. The communication between reader an tag is then analyzed, dimensions and further parameters of reader and tag antennas are discussed and a received power and Doppler shifts due to the tag motion are evaluated. It is shown, that the 2,45 GHz frequency band is a suitable choice for this application. |
